The aim of this paper is to analyze the number and error distributions of the FY-2C cloud drift wind (CDW) data using statistical methods, then use CDW data in numerical weather precipitation in southwestern China.By comparison and analysis, the main conclusions as following: (1) More than 80% available points of CDW data are concentrated in the 200~300hPa, but the total number during the day is more than the night; error statistical results of day and night show that the trend of the average error, standard error and RMS error is similar.(2) The vertical distribution of the available point number of CDW data in different regions have no significant difference, but the not-available points have contrary changes; At the same time, the errors in different regions have some regional characteristics, and in the plateau region are smaller than low altitude region.

2003年中央气象台于6-9月开展了为期4个月的全国地质灾害气象预警预报，在中央电视台向全国公众发布地质灾害气象预报和警报64期，引起了社会的广泛关注，收到了较好的社会效益。本文在收集整理2003年全国发生的地质灾情的基础上，分析研究滑坡、泥石流等地质灾害发生与西北太平洋和南中国海发生发展的热带气旋间的诸多观测事实，对年内发生的重大地质灾害过程同与之对应登陆影响的热带气旋进行了观测研究。
进入21世纪，人类对自己的生存环境—地球的未来更为关切。对比近百年来发生在地球上的急剧变化，气候的变暖、干旱、荒原沙漠的扩张、极冰雪盖的退缩暗示地球村的人们，要关注我们地球的未来，更要研究和了解它的过去。本文介绍了百年台风网站系统，浅谈了百年台风网页系统设计的主要特点。

“文革”期间,陈丕基在中国科学院南京地质古生物研究所图书馆阅览室的一堆废纸里偶然发现了翁文灏,用毛笔写的一封信,就将它拣出来收藏了很久。最近陈将此信交给石宝珩,认为可能有史料价值。石宝珩又向潘云唐咨询信中提到的人物。潘云唐作答：收信人建猷是尹赞勋,赓阳是李春昱；信中提到的谢季骅是谢家荣,孙铁仙是孙云铸。笔者反复欣赏这封简短的信,首先对它的内容感觉兴趣,信上主要谈了中国地质学会第20届年会的地点问题
